/wait

Simple utility to test the availability of TCP connections. Intended for environments, where a certain startup order is important (eg. multi-container Docker applications).

Usage

Wait tries to connect to a TCP connection within the given timeout. The scripts exits with 0 on success, 1 otherwise.

Usage of ./wait:   
  -address string     a hostname or ip-address including port. Eg. 127.0.0.1:80
  -timeout int        a timeout in seconds or 0 for no timeout (default 10)

Examples

wait -address <hostname-or-ip>:<port> -timeout <timeout-in-seconds>
wait -address nginx:443 -timeout 10
